Ingredients & Preparation Notes

- Mixed Mushrooms: A variety like cremini, shiitake, and oyster adds different textures and flavors. Sautéing them well ensures a concentrated taste.
- Chestnuts: Use cooked chestnuts for ease. They add a nutty flavor and creamy texture to the filling.
- White Miso Paste: This adds a unique umami flavor. Look for a mild, white miso for the best balance.
- Vegan Puff Pastry: Thaw it properly to ensure it’s pliable and easy to work with.
- Substitutions: For gluten-free, use a gluten-free puff pastry. If soy-free, replace miso with tamari or coconut aminos.
Professional Tips & Techniques
- Roasting Squash: Roast at 400°F (200°C) to caramelize the sugars, enhancing flavor and texture. Spread cubes evenly for consistent cooking.
- Sautéing Mushrooms: Cook mushrooms until they release their moisture and brown, which concentrates their flavor. Add miso towards the end to preserve its delicate taste.
- Cooling the Filling: Let the filling cool completely before wrapping in pastry to prevent a soggy bottom. This step is crucial for a crisp, flaky result.
- Sealing the Pastry: Brush the edges with water before sealing to ensure they stick well. Crimp with a fork for both function and aesthetics.
- Baking: Bake at 400°F (200°C) until the pastry is golden and puffed, typically 35-40 minutes. Check for doneness by looking for a deep golden color and flaky texture.
Recipe Variations
- Herb Variations: Swap thyme for rosemary or sage for a different aromatic profile.
- Nutty Additions: Include walnuts or pecans for extra crunch and flavor.
- Spiced Version: Add a pinch of nutmeg or cinnamon to the squash for a warm, spiced note.
- Gluten-Free Option: Use a gluten-free puff pastry to cater to dietary restrictions.
- Soy-Free: Replace miso with tamari or coconut aminos for a soy-free alternative.
- Cheese Lover’s Twist: Incorporate vegan cheese for a melty, indulgent touch.
- Seasonal Adaptations: In summer, try with roasted zucchini or eggplant; in winter, add Brussels sprouts or kale.
- Flavor Boost: Mix in some balsamic vinegar or vegan Worcestershire sauce for added depth.

Vegan Miso Mushroom, Squash and Chestnut Wellington
Equipment
- Baking sheet
- Large skillet
- Rolling Pin
- Pastry brush
Ingredients
- 1 medium butternut squash peeled, seeded, and cut into 1-inch cubes
- 1 pound mixed mushrooms such as cremini, shiitake, and oyster, sliced
- 1 cup cooked chestnuts roughly chopped
- 2 tablespoons white miso paste
- 2 cloves garlic minced
- 1 tablespoon fresh thyme chopped
- 2 tablespoons olive oil
- 1 sheet vegan puff pastry thawed if frozen
- 1 tablespoon soy milk for brushing
Instructions
- Preheat your oven to 400°F (200°C). Toss the butternut squash cubes with 1 tablespoon of olive oil, salt, and pepper. Spread them on a baking sheet and roast for 25-30 minutes until tender and slightly caramelized.
- In a large skillet, heat the remaining olive oil over medium heat. Add the mushrooms and sauté until they release their moisture and start to brown, about 10 minutes. Stir in the garlic, thyme, and miso paste, cooking for another 2-3 minutes until fragrant.
- In a large bowl, combine the roasted squash, sautéed mushrooms, and chestnuts. Season with salt and pepper to taste. Allow the mixture to cool slightly.
- Roll out the vegan puff pastry on a lightly floured surface to a rectangle about 12x14 inches. Spoon the filling along the center of the pastry, leaving a 2-inch border on all sides.
- Fold the pastry over the filling, pinching the edges to seal. Use a fork to crimp the edges for a decorative touch. Brush the top with soy milk for a golden finish.
- Transfer the wellington to a baking sheet lined with parchment paper. Bake at 400°F (200°C) for 35-40 minutes, or until the pastry is golden brown and puffed.
- Allow the wellington to rest for 10 minutes before slicing and serving.
